GAS-BURNER.

SPECIFICATION forming part of Letters :Patent No. 558,845, dated April 21, 1896. Application tiled June 4,1895. Serial No. 551,652x (No model.)

To a/ZZ whom, t may concern:

Be it known that I, PETER ROHRBACI-Lof Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gas-Burners,of which the following is a specification.

The object of my invention is to provide a gas-burner specially designed for heating for the purpose of convertingV at will an ordinary kitchen stove or range into a gaslstove, thus saving valuable space in the kitchen and permittin g the ordinary pot-holes of the kitchenstove to serve as the supports for the utensils when the stove is used for a gas-stove.

My invention consists in the peculiar construction and arrangement of the gas-burners,

as will be hereinafter fully described.

Figure l is a vertical section of a stove or range with my gas-burner applied to the same and also shown in section. Fig. 2 is a plan view of the gas-burner alone.

In the drawings, a is the ire-pot of any ordinary stove, and a' the grate-bars.

The burner comprises a hollow base b, of circular or other approved form, which has a raised central projection screw-threaded on its inner side to receive the screw-threaded end of the vertical burner-tube c. The upper end of the burner-tube screws into a screwthreaded enlargement on the lower side of the burner-head, which consists of a hollow crosspiece d, terminating at each end 'in a hollow annular burner cl2 cl2, communicating with the channel or duct in the cross-piece and having numerous perforations on the upper side to permit of the escape of the burning jets of air and gas.

In the base Z1 of the burner there is arranged a gas-inlet pipe c, whose end is turned up concentrically with the burner-tube c and joins onto a nozzle e', extending up to the level of air-inlet holes c', formed in the tube c, which holes enter obliquely and converge upwardly, so as to give a free upward induction of air to be drawn in by the jet of gas escaping from the nozzle of pipe e. To fix this gas-supply pipe e and its nozzle e rigidly in concentric relation to each other and securely against any tendency to become loose and leaky in the tube c, an intermediate sleeve f is used,which is screw-threaded upon its exterior and is made to engage screw-threads on the interior of the tube c, and is also screw-threaded 1nteriorly and is made to engage screw-threads on the adjacent abutting ends of thegas-pipe e and nozzle e. This forms a very strong, tight, and safe joint.

The horizontal portion of pipe c passes laterally through an opening in the base b and thence out through an opening g in the door g in the stove or range, and connects with a flexible hose h, which may be adjusted at will to any of the gas-pipe fixtures of the house, or any other suitable source of supply.

The head of the gas-burner is to be constructed of such dimensions as to bring its annular burners d2 immediately beneath the pot-holes a2 of the stove, so that said pot-holes form the support for the various kitchen utensils when the stove is used as a gas-stove, as well as when used with solid fuel.

I am aware of the Patents Nos. 338,143, 411,648, and 457,245, and make no claim to anything shown therein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A gas-burner comprising a hollow base with raised central projection screwthreadled interiorly, avertical burner-tube c screwed into the same and having air-holes in its side, a gas-supply pipe e passing horizontally into the base and then turned up into vertical po sition concentrically to the burner-tube, a nozzle e joining onto the upturned end of pipe c and extending to about the level of the air-holes, said nozzle and gas-pipe being threadedvexternally at their meeting ends, and a coupling-sleeve f screwthreaded both upon its outside and inside and meshing with threads on the outside of the meeting ends of the gas-pipe e and nozzle'e to connect the two, and also meshing with the threads on the inside of the burner-tube substantially as shown and for the purpose described PETER ROHRBACI-l.
